When you change steering geometry only on a few parts and not all parts are matched, you can achieve the stance but another component of the geometry will suffer and carry more load than it's designed for...It's like tuning a guitar, all the strings need to be tuned not just 5 of them. Ergo the phrase, "tuning a suspension". In this case cutting springs to get a desired ride height and not following through with the rest of the parts will result in premature wear in other parts of the steering mechanism.
